What do you say? I would suggest that you benchmark this for yourself. I found pretty good results using e4rat along with systemd readahead. It will end up taking quite a bit longer in "initrd" that way, but once it starts booting services end up taking a lot less time. A friend of mine, however, had bad results doing this, and found that Preload did a better job with Readahead and e4rat. He didn't have the benchmarks to back up his assertation tho. So ymmv, but make sure you're using some tool to benchmark the performance. What "feels" faster isn't always.
